I'm not sure how much value this has, but on the face of it, it seems interesting to see how well we, as photographers, are able to see and match colours and levels of saturation and generally perceive colours.
I often wonder how my dad (who is red/green colourblind) would cope with editing a picture of a holly bush, given he can't easily see the red berries on it.
Anyway, let me know what you think. My best score so far is 9.3.
